Shrub rose plant named ‘CHEwpeachdell’

ABSTRACT

A new variety of Shrub rose suitable for garden decoration, having flowers of peach coloration.

Classification: The present invention relates to a new Rosa hybridaplant.

Variety denomination: The new plant has the varietal denomination‘CHEwpeachdell’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Shrub Rose. Thevarietal denomination of the new variety is ‘CHEwpeachdell’. It has asits seed parent the variety known as ‘CHEwarvel’ (U.S. Plant Pat. No.9,012) and as its pollen parent the variety known as ‘DICmagic’ (notpatented).

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from otherpresently available and commercial rose cultivars known to the inventorare the following combination of characteristics: its very upright tonearly columnar habit, its numerous petaloids in the flower, its nearlyflat upper side of the rachis, its red pigmentation on the rachis andthe stipule of the young leaf and its lack of extension in bud lengthfrom before the calyx breaks to after the calyx breaks. The plant has avery upright to nearly columnar growing habit, suitable for outdoorgarden decoration.

Asexual reproduction of the new variety by budding as performed in KernCounty and Upland, Calif., shows that the foregoing and otherdistinguishing characteristics come true to form and are established andtransmitted through succeeding asexual propagations. ‘CHEwpeachdell’ maybe asexually propagated by cuttings, budding and grafting.

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, ‘CHEwarvel’ bythe following combination of characteristics: ‘CHEwpeachdell’ usuallybears clusters of flowers of peach coloration, whereas ‘CHEwarvel’ bearsflowers of medium yellow coloration with less clusters. The new varietyis classified as a shrub with a very upright to nearly columnar growthhabit, whereas the seed parent is classified as a climbing miniaturewith a more spreading growth habit.

The new variety may be distinguished from its pollen parent, ‘DICmagic’by the following combination of characteristics: whereas ‘CHEwpeachdell’bears double (about 26 to 32 petals and about 22 to 30 petaloids)flowers of peach coloration, ‘DICmagic’ bears flowers of orange andyellow coloration with significantly less petalage and petaloides. Thenew variety is classified as a shrub with a very upright to nearlycolumnar tall growth habit, whereas the pollen parent is classified hasa miniature with a more compact and significantly shorter growth habit.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows theflowering thereof from bud to full bloom depicted in color as nearlycorrect as it is possible to make in a color illustration of thecharacter. Throughout this specification, color references and/or valuesare based upon The Colour Chart of The Royal Horticultural Society(1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the newvariety grown outdoors in Upland, Calif. in the month of September.Phenotypic expression may vary with environmental, cultural and climaticconditions, as well as differences in conditions of light and soil.

FLOWER

The new variety sometimes bears its flowers singly, usually in clustersof two to five or more per stem. Flowers may be borne in regular roundedto somewhat flat clusters on strong somewhat short to medium lengthstems (about 28 to about 75 cm.). Outdoors, the plant blooms abundantlyand nearly continuously during the growing season. The flowers have aslight tea fragrance.

BUD

The peduncle is about 1.2 to about 3.6 cm. in length, of somewhatslender to average caliper (about 0.15 to about 0.3 cm. in diameter),and usually erect. It is moderately smooth, with some stipitate glands,and some hairs. Peduncle color is between 144A and 148A sometimes verylightly suffused, especially on the side exposed to the sun, with near183C.

Before the calyx breaks, the bud is about 0.8 to about 1.3 cm. indiameter at the widest point, about 1.5 to about 2.3 cm. in length, andpointed to moderately ovoid in shape. The surface of the bud bears somemoderately long slender foliaceous appendages and few stipitate glands,usually with slender entire foliaceous parts extending beyond the tip ofthe bud about ¼ or more of its length. Bud color is between 144A and147B sometimes lightly suffused, especially on the side exposed to thesun, with between 187B and 183B.

The sepals are about 1.7 to about 2.1 cm. in length and about 0.6 toabout 0.8 cm. in width at the widest point. The outer surface color ofthe sepal is between 144A and 147B sometimes lightly suffused,especially on the side exposed to the sun, with between 187B and 183B.The inner surface color of the sepal is between 138B and 137C andcovered with fine wooly tomentum; sepal margins are lined with fewstipitate glands and hairs.

As the petals open (after the calyx breaks), the bud is about 1.4 toabout 1.9 cm. in diameter at the widest point, about 1.6 to about 2.1cm. in length, and moderately flat-topped to globular in form. The colorof the under and upper surfaces of the newly opened petals is between28B and 26D. At the point where the petal attaches on the uppersurfaces, there is a moderately small zone of between 14B and 13B. Atthe point where the petal attaches on the under surfaces, there is asmall zone of near 13C.

BLOOM

When fully open, the bloom ranges from about 4.4 to about 5.6 cm. indiameter. The flower receptacle size is about 0.7 to about 1 cm.Petalage is double with about 26 to 32 petals and about 22 to 30petaloids irregularly arranged. When partially open, the bloom form ismoderately cupped to globular, and the petals are moderately tightlyspiraled to cupped with petal edges somewhat reflexed outward. Whenfully open, the bloom form is less cupped, and the petals are moreloosely to slightly cupped with petal edges somewhat reflexed outward.

PETALS

The substance of the petals is moderately heavy and of medium thickness,with upper surfaces moderately shiny to slightly satiny and undersurfaces matte to somewhat shiny. The outer petals are nearly obovate tosomewhat oval in shape with usually mucronate to sometimes roundedapices. The inner petals are nearly obovate to somewhat oblanceolate inshape with usually mucronate to sometimes rounded apices. The petals areabout 1.5 to about 2.4 cm. in length and about 0.7 to about 2.1 cm. inwidth at the widest point. Petal margins are entire.

NEWLY OPENED FLOWER

The under surface color of the outer, intermediate and inner petals isbetween 28C and 29C. At the point where the petal attaches, there is amoderately small large zone of between 12B and 13C.

The upper surface color of the outer, intermediate and inner petals isbetween 28B and 29B. At the point where the petal attaches, there is amoderately small zone of near 12B.

The general tonality of the newly opened flower is between 28B and 29B.

The flower contains about 22 to 30 petaloids irregularly arranged. Thesubstance of the petaloids is moderately heavy and of medium thickness,with upper surfaces moderately shiny to slightly satiny and undersurfaces matte to somewhat shiny. The petaloids are nearly obovate tosomewhat oblanceolate in shape with usually mucronate to sometimesrounded apices. The under surface color of the petaloids is between 28Cand 29C. At the point where the petaloids attaches, there is amoderately small zone of between 12B and 13C. The upper surface color ofthe petaloids is between 28B and 29B. At the point where the petaloidsattaches, there is a moderately small zone of near 12B. The petaloidsare about 0.5 to about 1.2 cm. in length and about 0.3 to about 0.6 cm.in width at the widest point. Petaloids margins are entire.

THREE-DAY-OLD FLOWER

The under surface color of the outer and inner petals is between 38D and36C. At the point where the petal attaches, there is a moderately largezone of between 12D.

The upper surface color of the outer and inner petals is between 38C and20D. At the point where the petal attaches, there is a moderately largezone of between 8C and 10C.

The general tonality of the three-day-old flower is between 38C and 20D.

On the spent bloom, the petals usually drop off cleanly.

In September in Upland, Calif., blooms on the bush growing outdoorsgenerally last about four to five or more days. Cut roses from plantsgrown outdoors and kept at normal indoor living temperatures generallylast about four to five or more days.

MALE REPRODUCTIVE ORGANS

Stamens vary in number (average about 61) and are arranged regularlyabout the pistils; many are mixed with petaloids. The filaments are ofmedium length (about 0.6 to about 0.9 cm.), most with anthers. Filamentsare between 13A and 14B in color. The anthers are somewhat small for theclass and all open approximately at the same time. Anther color isbetween 22A and 26A when immature and between 164C and 165A at maturity.Pollen is abundant.

FEMALE REPRODUCTIVE ORGANS

Pistils vary in number (average about 69). The styles are moderatelyeven, somewhat short in length (about 0.2 to about 0.5 cm.), thin incaliper, and moderately loosely bunched. Stigma color is between 11C and13D. Style color is between 53A and 60A. Ovaries are usually allenclosed in the calyx.

Hips are of average length (about 1.7 to about 2.1 cm.), flat at the topand somewhat globular to urn-shaped in form, and between 30B and 30C incolor when ripe. The hip surface is very smooth with thick fleshy walls.The sepals are permanent. The seeds are irregularly rounded, smooth intexture, approximately 4 to about 8 per hip, about 0.3 to about 0.5 cm.in diameter at the widest point and between 164D and 163C in color.

FOLIAGE

The compound leaves are usually comprised of three to seven or moreleaflets and are borne abundantly. The seven-leaflet leaves are about7.8 to about 9.4 cm. in length and about 4.2 to about 5.8 cm. in widthat the widest point, moderately leathery to somewhat crisp in texture,and semi-glossy finish. The terminal leaflets are about 2.1 to about 3.6cm. in length and about 1.3 to about 2.0 cm. in width at the widestpoint, shaped narrowly oval to somewhat broadly lanceolate with mostlyacute to slightly acuminate apices and rounded bases. Their margins areusually simply serrate.

The upper surface color of the mature leaf is between 147A and 137B. Theunder surface color of the mature leaf is between 147B and 138B. Theupper surface color of the young leaf is between 146A and 144A,sometimes moderately suffused especially toward the very edge of theleaves with between 187C and 183C. The under surface color of the youngleaf is between 146B and 138B, sometimes moderately suffused withbetween 187C and 183C.

The rachis is light in caliper and moderately rough. The upper side isnearly flat to very shallowly grooved with many hairs and very fewstipitate glands on the edges of the grooves. The under side of therachis is moderately rough with some hairs and stipitate glands and afew small prickles. The rachis color is between 146C and 146B,moderately suffused on the young leaf with between 187C and 183C.

The stipules are about 0.9 to about 1.3 cm. in length and of mediumwidth (about 0.3 to about 0.5 cm.) with moderately short to mediumstraight points that usually turn out at an angle of more than 45degrees and sometimes slightly recurve toward the stem. The stipulescolor is between 146C and 146B, moderately suffused on the young leafwith between 187C and 183C.

The petiole is about 0.4 to about 1.0 cm. in length and about 0.1 toabout 0.15 cm in diameter at the widest point. The petiole color isbetween 146C and 146B.

The plant displays an above average degree of resistance to powderymildew and rust as compared to other commercial varieties grown undercomparable conditions in Upland, Calif. The plant's winter hardiness anddrought/heat tolerance are yet to be determined.

GROWTH

The plant has a very upright to almost columnar tall growing habit(about 175 to about 250 cm. in height and about 88 to about 125 cm.spread at the widest point), with very full branching. It displays veryvigorous growth and the canes are of somewhat light to medium caliper.

The color of the major stems is between 146C and 146D. They bear manylarge prickles that are about 0.5 to about 1.0 cm. in length. The largeprickles are almost straight to angled slightly downward with a verylong moderately narrow oval base; prickle color is between 166B and166C. The major stem bears few small prickles of similar shape andcoloration.

The color of the branches is between 146B and 147B. They bear many largeprickles which are of similar size and shape to the large prickles onthe major stems; prickle color is between 162C and 160B sometimeslightly suffuses near the base with near 182C. The branches bear fewsmall prickles of similar shape and coloration.

The color of the new shoots is between 144A and 148A sometimesmoderately suffused especially on the side facing the sun with between187C and 183C. They bear some large prickles which are of similar sizeand shape to the large prickles on the major stems. The shoots bear veryfew small prickles of similar shape and coloration. Prickle color isbetween 187C and 185C.
